How to use this LeBlanc counter guide
the best way to counter LeBlanc in Riftbound is to deny her clean conquers and holds, answer the source unit her copies are built around instead of the copies themselves, and refuse to feed her Deathknell value by chumping into LeBlanc - Fragmented. If you kill the wrong thing at the wrong time, you are not disrupting her engine - you are powering it.

Open deckLeBlanc is not a beatdown deck and she is not a control deck. She is an engine. LeBlanc - Deceiver wins by turning a single good battlefield into a Reflection token, and then turning that token into card advantage, until one lane quietly becomes a scoring machine while you are still trading one-for-one somewhere else.
That is what makes the matchup uncomfortable. Nothing LeBlanc does looks lethal in isolation. She discards a card, exhausts her legend, and makes a Temporary copy of a unit already standing at a battlefield. On its own that is a small play. Repeated three or four times, backed by Deathknell payoffs and cheap gear, it is a resource lead you cannot out-grind.

LeBlanc, Deceiver: Why This Matchup Is An Engine Fight

Mind/Order Legend
LeBlanc - Deceiver
Her copy trigger only fires when she conquers or holds, so denying clean battlefield control shuts the whole engine off.

Mind Unit
LeBlanc - Everywhere At Once
Backline plus Temporary suppression makes her a protected engine piece; answer her before the copies start compounding.

Order Unit
LeBlanc - Fragmented
Her Deathknell rewards LeBlanc for letting units die, so removal that simply kills her can be exactly what she wants.
LeBlanc arrived in Unleashed as one of the strongest legends in the set, and for good reason. Her ceiling in best-of-one and casual play is Tier 1: she gets to do her thing uninterrupted, and her thing snowballs. In flexible best-of-three regional play she is more exploitable, because that is where disciplined interaction and a real sideboard can break the engine before it pays off. The key phrase there is *before it pays off*. This matchup is not decided by who has the bigger board. It is decided by whether you can shut off her copy loop while it is still small.
Her legend text is the whole game plan: when you conquer or hold, you may discard 1 and exhaust me to play a ready Reflection unit token there. It becomes a copy of another unit there. Give it Temporary. Read that carefully, because every counter idea in this guide comes out of it.
Three conditions have to line up for LeBlanc to get value:
Every one of those is a pressure point. The counter rule for the entire matchup: make at least one of those three conditions expensive on every turn that matters.
What The LeBlanc Deck Is Actually Trying To Do
Most LeBlanc lists are built around the Deathknell keyword. The Temporary tokens her legend creates are *supposed* to die - they expire at the start of her turn - and the deck is designed so that when they die, something good happens.
The clearest example is LeBlanc - Fragmented. Her text reads Assault, Deathknell: Draw 1. If it's your Beginning Phase, draw 2 instead. Copy Fragmented into a Temporary token, let the token expire on the Beginning Phase, and LeBlanc draws two cards for free. Do that repeatedly and she simply never runs out of gas. This is why the deck is often called Deathknell LeBlanc - the copies are not there to attack, they are there to die on cue and refill her hand.
Around that core the shell wants to:
That means the matchup is not solved by "kill her stuff." Sometimes killing her stuff is exactly the free Deathknell she wanted. Before every fight, ask the real question: which card is generating the value, and does answering it actually stop the engine - or feed it?
The Source-Unit Rule: Answer The Copy Target, Not The Copy
Here is the single most important idea in the matchup, and the one most players get wrong.
LeBlanc's Reflection token becomes a copy of another unit there. The token is Temporary - it is going to disappear on its own. The unit it is copying is not. So when you point removal at the shiny copied threat, you are usually spending a card to kill something that was leaving anyway, while the *source* - the real unit her whole plan is built around - stays safe and gets copied again next turn.
The disciplined line is to answer the source unit before the copy turn happens, or at the exact moment it would be copied. If Card Sharp is the body she keeps duplicating for Gold gear, kill Card Sharp. If a Deathknell attacker is the engine she is protecting, contest it on your terms. Killing the Temporary Reflection is almost always a tempo loss for you and a non-event for her.
She leans on this, which is why the deck runs *redundancy* rather than a single removal-protection spell. LeBlanc has three separate ways to make a copy - her legend, Mirror Image, and Keeper of Masks - so killing one Reflection token accomplishes nothing; another one is a single card away. That redundancy is the point: spend your interaction on the *source*, the value body every copy is built from, and answer it at a moment it actually stays dead, ideally before a second copy source is online to rebuild the board.
Use the card database here to line up removal that is hard to play around: effects that hit on entry, punish her at the battlefield, or answer the source before she floods the lane with copies.
LeBlanc - Everywhere At Once Is The Protected Engine
Everywhere At Once is the card that makes the whole thing feel oppressive. Its text is Backline (I must be assigned combat damage last) and your Temporary effects at my battlefield don't trigger.
Two things follow. First, Backline means she does not have to expose the engine to your attackers - she can copy and grind from behind a wall of chumpable bodies while the piece you actually want to kill sits in the back. Second, the Temporary-suppression clause is not for you - it is for *her*, letting her stack her battlefield without her own Temporary reflections misfiring in the wrong place.
The counterplay is to make her battlefield with Everywhere At Once the one you attack into, not the one you avoid. If you let her set up a clean Backline engine and grind, you are giving the deck the exact texture it wants. Force her to defend that lane. Pressure a second battlefield so she cannot leave the engine parked safely. And when you do get a window on Everywhere At Once, take it - a copy engine with no protected home is dramatically weaker.
Refusing The Deathknell Trap
This is where good players lose to LeBlanc without realizing it.
LeBlanc - Fragmented also has Assault (+1 Might while attacking), so she attacks bigger than she blocks. The instinct when a 3-cost attacker crashes in is to trade or chump-block. Against a Deathknell unit - Fragmented, or a Black Rose Dignitary that channels a rune when it dies - that instinct is a trap: when the unit dies, LeBlanc gets paid, and if Fragmented dies into her Beginning Phase, she draws two. You spent a card and a body to hand her exactly the fuel her engine runs on.
The counter is patience, but not passivity:
A good rule: if removing or trading with a unit gives LeBlanc a card, you need a reason beyond "it was there." Spend the interaction because the score or the engine changes if you do not - not because you can.
Mirror Image: The Signature Second Engine

Mind/Order Spell
Mirror Image
Her signature spell copies any unit into a Temporary Reflection at her base with no conquer or hold required - a second copy engine that keeps grinding even on turns you deny her a battlefield.
Here is the card the copy plan is actually built on, and the one most matchup prep forgets: Mirror Image, LeBlanc's signature spell. Its text: Choose a unit. Play a ready Reflection unit token to your base. It becomes a copy of that unit. Give it Temporary.
Read what that does to your counterplay. Her legend needs a conquer or hold to copy. Mirror Image does not - she can duplicate any unit on the board straight to her base, for three energy, whenever she likes. So the clean-looking turn where you finally deny her a battlefield is not the shutout it feels like: she can still Mirror Image your best unit or her own value body, bank a Deathknell trigger or a Gold token, and keep the grind going. Note the wording is "choose a unit," not "a friendly unit" - a well-built LeBlanc can even copy *your* threats.
The counterplay is not to respect some specific protection spell - she does not really have one. It is to understand that LeBlanc has *multiple* copy sources (Deceiver, Mirror Image, Keeper of Masks) and only a couple of *source units worth copying*. You cannot answer the copies; there are too many, and they were leaving on their own anyway. You answer the handful of units the copies are made from, and you keep her off the battlefields where a copy board would score.
How LeBlanc Actually Closes The Game
LeBlanc does not have a dedicated "press button, score points" engine, and it is worth saying plainly, because the way she actually wins is subtler and easier to ignore: she out-cards you, then converts a board she can rebuild for free into battlefield control, and battlefield control into the victory-point total.
Every Deathknell draw off Fragmented, every Gold token off Card Sharp or Plundering Poro, every free Reflection body off Mirror Image or Keeper of Masks is one more resource than you have. Do that for six or eight turns and she is holding more cards, more bodies, and more board than you can contest - and holding a battlefield *is* how you score in Riftbound. The "conversion turn" is not one card. It is the moment her resource lead is large enough that she holds two lanes at once and you can only fight for one.
That is your clock. Treat a wide, uncontested LeBlanc board as the alarm bell: the longer she is allowed to sit on copies and Deathknell draws, the closer she is to scoring from a position you cannot break. Contest the battlefields she wants to hold, and race the point total before her card advantage makes every lane hers.
The Zero Drive And Late-Game Payoffs

Mind Gear
The Zero Drive
A late-game payoff that dumps banished units back onto the board; keep pressure on so she never reaches this turn.
The Zero Drive is the reward for a game that goes long. It equips, banishes units under it, and later - for a big Mind cost - plays all units banished with it, ignoring their costs. In a deck already flooding the board with cheap bodies and Reflection tokens, that late board dump can rebuild an entire scoring position at once.
You do not beat The Zero Drive by answering it after it fires. You beat it by making sure LeBlanc never gets to the turn where it matters. Every turn you keep her defending, off-balance, and unable to freely copy is a turn she is not assembling her top end. If the game is stretching and LeBlanc is untapped and comfortable, you have already lost the pace battle - tighten the clock.
Turn By Turn Counter Plan
Turns 1-2: Deny The First Clean Conquer
LeBlanc's engine cannot start until she conquers or holds a battlefield with a unit worth copying. Your first job is to make those early battlefields contested. A hand that lets her walk onto an open lane, hold it, and copy Card Sharp or Plundering Poro on turn two is a hand that lets the snowball start for free.
You do not need to overextend. You need to make her *fight* for the first battlefield she wants to copy from, so the copy either does not happen or costs her a real card and a combat.
Turns 3-4: Answer The Source, Not The Reflection
This is where the matchup usually turns. Identify the unit her copies are built around - the Card Sharp, the Gold-gear body, the value unit behind Everywhere At Once - and spend your best answer on *that*, at a moment it actually stays dead rather than getting remade by a second copy source. Let the Temporary tokens expire on their own; they were leaving anyway.
Do not point premium removal at a copy just because it is the biggest thing on the board. Point it at the card that keeps generating the copies.
Turns 5-6: Don't Feed The Deathknell
By now Fragmented, Black Rose Dignitary, and other Deathknell bodies are in the mix. Stop auto-trading. Every time you kill or chump a Deathknell unit, check whether you are handing LeBlanc a payoff - and whether it is her Beginning Phase, which upgrades Fragmented to draw two. Answer Deathknell units on your terms, or leave them and attack elsewhere.
Late Game: Close Before The Grind Runs Away
If LeBlanc reaches the turns where her card advantage snowballs or The Zero Drive dumps a board, the grind has gone her way. Keep a clock alive the whole game so the match ends before her top-end payoffs come online. The best anti-LeBlanc games are not pure defense - they are games where she is always one battlefield behind and never gets a free turn to build.
Mulligan Guide Against LeBlanc
Keep hands that can do at least two of these:
Ship hands that are pure late-game value. A pile of expensive cards and one reactive spell loses to LeBlanc, because she out-grinds value decks by definition - her whole plan is generating more resources than you. Against her, a *functional* proactive hand beats a *powerful* slow one every time.
Sideboard Plan Into LeBlanc
If you use a sideboard, build a real eight-card plan instead of a pile of maybes. A strong first LeBlanc package usually looks like this:
The big warning: do not overboard into slow control. If you cut too much pressure, LeBlanc gets to spend every turn improving her own hand, and the copy-plus-Deathknell engine out-values you. You want *better interaction*, not a *slower deck*.
Matchup Plans By Archetype
Aggro And Pressure Decks
You are the favorite if you respect the traps. Force early battlefield fights so her first copy never happens for free, and do not chump Deathknell attackers just to save chip damage. Spread pressure across lanes so Everywhere At Once cannot hide the engine and she cannot rebuild a board faster than you break it. Close before her card advantage snowballs.
Midrange Decks
You have the tools to win a clean game, but the highest risk of getting out-valued if you settle into pure trading. Answer the source unit, keep a threat on board every turn, and make sure your removal is not just feeding Deathknell draws. If you trade one-for-one forever, her extra cards pull ahead.
Control Decks
Do not pretend the matchup starts on turn six. LeBlanc grinds control by design. You need early speed bumps, removal that hits the source before she has a second copy source to remake it, and a way to punish The Zero Drive and a wide copy board. The control player who waits for the perfect answer usually loses because LeBlanc simply drew more cards first.
Combo And Engine Decks
Your priority is buying clean setup turns without letting LeBlanc own a battlefield permanently. Keep interaction that can deny her conquer while you assemble. If your engine can force her to defend, the copy loop stalls and you get the tempo you need.
What To Test On RiftStorm
This article should become reps, not just reading. Use Riftbound Counters to map LeBlanc against the rest of your expected room, then build two lists in the deck builder: your real deck and a LeBlanc test list. Goldfish her copy engine so you understand exactly when the conquer-or-hold trigger fires and how fast Fragmented refills her hand.
Search the card database for hard-to-dodge removal, cheap contest units, recall effects, and answers to protected Backline engines. Then browse community decks to see how other players are attacking the matchup, and compare your theory against real lists.

If the answer is no to two or more of these, the matchup needs more work.
Bottom Line
LeBlanc is a top-tier Riftbound engine legend because she turns one good battlefield into repeated value. She conquers or holds, discards and exhausts to make a Temporary Reflection, copies a source unit, and loops that copy into Deathknell draws and gear until the game is quietly out of reach.
You beat LeBlanc by making the engine expensive. Deny her clean conquers. Answer the source unit, not the copy. Refuse to feed Fragmented free Deathknell draws. Spread your pressure so no single answer of hers swings the game and Everywhere At Once has nowhere safe to hide. And keep a clock alive so the game ends before her card advantage and The Zero Drive get to cash out.
That is the difference between losing to the idea of LeBlanc and beating the actual deck across the table.
Frequently Asked Questions
What is the best LeBlanc counter plan in Riftbound?
The best plan is to deny her conquer-or-hold triggers, answer the source unit her Reflection tokens copy instead of the copies themselves, and refuse to feed LeBlanc - Fragmented free Deathknell draws. Keep pressure on so she never gets a clean turn to build the engine.
Should I kill LeBlanc's Reflection tokens?
Usually no. Reflection tokens are Temporary and expire on their own, so removal spent on them is a tempo loss - and she has several ways to remake them (her legend, Mirror Image, Keeper of Masks). Point your answers at the source unit - the Card Sharp, the Gold-gear body, or whatever value body her copies are built around - because that is what keeps regenerating the threat.
How do I sideboard against LeBlanc?
Bring cheap contest units, hard-to-dodge removal for source units and for LeBlanc - Everywhere At Once, one recall or reset to undo a copy turn, and enough proactive threats to keep a clock. Do not overboard into slow control, because LeBlanc out-grinds passive decks.
Is LeBlanc still worth respecting in the Unleashed meta?
Yes. She is one of the strongest legends in Unleashed and dominant in best-of-one and casual play. In best-of-three she is more exploitable, but only if you sideboard correctly and attack the engine - she remains one of the first decks a serious list should test against.
